Single Phase Full-wave Driver for Fan Motor

TC78B002FTG is a single phase full-wave driver for fan motor. It has a DMOS device in an output transistor.

A highly effective drive is possible by adopting a DMOS output driver with low ON resistance and a PWM drive system.

Features

• Single-phase full-wave drive

• Motor power supply voltage: VM =16V (maximum operating range)

• Output current: Iout = 1.5A (max.)

• PWM control

• Built-in oscillation circuit (External resistor)

• Soft switching drive

• Lock protection, Automatic recovery

• Quick start

• Built in hall bias

• Rotation Speed Detection (FG) and Lock Detection (RDO) Output

• Current limit function

• Built in over current protection

• Built in thermal shut down circuit
